EUA6204
1.36-W Mono Fully Differential
Audio Power Amplifier
DESCRIPTION
The EUA6204 is a mono fully-differential audio
amplifier, capable of delivering 1.36W of continuous
average power to an 8Ω BTL load with less than 1%
distortion (THD+N) from a 5V power supply, and
720mW to a 8Ω load from a 3.6V power supply.
The EUA6204 is ideal for PDA/smart phone application
due to features such as -80-dB supply voltage rejection
from 20Ha to 2kHz, improved RF rectification immunity,
small 20mm
2
PCB area, and a fast startup with minimal
pop.
The EUA6204 is available in a MSOP-8 and in the
space-saving 3mm
×
3mm DFN package.
